PURPOSE:To precisely collect a ticket printed out erroneously or excessively by displaying data corrected or changed after summing operation when an error is generated during the issue of the ticket or the order is changed by a customer's request. CONSTITUTION:When a regiser is set to a register mode and divisional codes and values are inputted from a keyboard 6 through a keyboard/display device controlling circuit 32, these inputs are stored in a RAM34 under the control by a CPU31 and a printer is driven by a printer driving circuit 37 through an I/O unit to print out 39 and issue a ticket. when the operation is executed in error or an order is changed by the customer, a correction key on a keyboard is depressed after summing the inputs of the customer to input the divisional codes and values of the unrequired ticket, so that the data are stored in a correc tion counter and displayed on a display device 2 and the unrequired value is subtracted from the sum. Consequently the unrequired ticket can be precisely collected. |
